Great information here. It appears that your current broker hasn't taken you through structuring your loans so you can keep buying (many brokers will give you the loan for this property but not the next, next and next - as happened to me, and I'm now trying to open up some equity so I can keep buying).
Give the brokers who have provided comment here a call, they can look at your whole situation, including where you are, and want to get to. It's great that people experienced in their field are willing to share their knowledge freely.
